TO ALL WHOM IT `MAY CONGERN:

Be it known that .1, OTIS T. BEDELL, of the city, county, and-State of New York, have invented a new and useful improvement in Slate Washers; and I do hereby declare that the following is. a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, in which- Y Figure 1 is a side elevation of a slate washer, constructed according to my invention.-

Figure 2`is a central vertical transverse section of the same. Similar letters of reference indicate corresponding parts in both figures.

This invention consists in a slate washer composed of aicompressible water receptacle formed of India rubber, or other suitable elastic material, and furnished with a wiper of sponge or other similar absorbent substance, whereby a very cleanly and convenient device-for washing slates is obtained, and one. that may be manufactured 'at an extremely moderate cost. A

'lo enable others, skilled in the art, to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawings.v v

The compressible vesselwhich constitutes the water receptacle of the washer is shown at A, and is made preferably of India rubber, and of a nearly spherical'shape`-and is furnished' with a hole or orifice, a through which'water may be poured intol the aforesaid vessel A, and'in which is inserted apiece, B, of sponge or other substance capable 0f readily absorbing water,`and also of yielding up the same by compression, the innermost end of such sponge, or substance, being expanded ivithin the interior of the vessel A as .shown in iig, 2, while the outer end thereof is spread out or expanded at theexteriorfof` the same, as represented in both the figures. That sideof the-*vessel A opposite the orifice a, is made flat, -or slightly concave, as at b b, in order to form a bottom which willv retain the lvessel A in position, with the wiper B uppermost, when placed upon a. flat ysurface when not in use. The vessel A is first partially illed with water, as shown at in iig. 2, and the -wiper B is then inserted in the orice a a, as hereinbeforc set forth, with its lower4 endat a slight dis,-

tance from the'surface of the water in the vessel A, when thel said vessel is' in an upright position as just hereinbefore explained, in order that the water may notl pass upward and saturate the wiper B` wheni the device is "not infuse. In. using the Washer, the v essel A is grasped in the hand,and is. compressed until the water is forced upward 4in contact with the nnermost'portion of the Wiper B, ,whereupon a sufficient quantity of water"- passes `through the said wiper by capillary attraction to properly moisten the outermost portion of the same; which being done, and the vessel Astill held in.tl1 e-hand, the Wiper B is applied to the surface of the slate to wash or cleanse the sam'e, in substantially the same manner as an ordinary sponge. If desired, a perforated partition maybeplaced midway between the vupper andi-lower portions of the vessel A, in order to reduce, in

a measure, the sudden ilowing of the water v to the upper.part thereof when the samel is tilted or turned over.

If desired, the Ivessel Amay be made of hemispherical gr other suitable form, but it is preferred to have it of nearly sphericalv shape, as hereinbefore described," inasmuch as in this case, by removing the wiper B, and emptying the water from the vessel A,.tl1e said vessel may be used* as a common toy ball, thus adapting the device to the amusements of children, as well as to use in washing slates.

What claim as new, and desire to secure by Letters Patent, is i A slate washer composed of a compressible water vessel A, and absorbent Wiper B, combined substantially as herein set forth.
